nth term = term x 2
the nth term is basically a number in the sequence.
for example:
50 = 25 x 2 |

@cer
the Nth term has to mean the term number like this
1,2,4,8,16
1 2 3 4 5 _________ 1 2 4 8 16 |

@super
you didn't give me a formula and you didn't explain anything
I already know that you have to double it but
n=term number
not the actual term |

that's what i am trying to say
nth term is basically the order it goes in
if you going to work out 50th term, look at the difference between all of them. Now that we know it is x2 put it in the formula
nth(term) = n(number) x 2 |
